Distance-adjustable synchronous roller

Abstract

The invention discloses a distance-adjustable synchronous roller which comprises a support and eccentric sleeves. The support comprises a left side plate and a right side plate, and two eccentric sleeve mounting holes are vertically formed in each of the left side plate and the right side plate. Each eccentric sleeve comprises a disc and a neck sleeve arranged on one side face of the disc, and aneccentric hole is formed in the middle of each disc. One eccentric sleeve is mounted in each eccentric sleeve mounting hole, the neck sleeve of each eccentric sleeve is inserted into the correspondingeccentric sleeve mounting hole, the eccentric sleeves on the left side plate and the eccentric sleeves on the right side plate are symmetrically mounted, and the neck sleeves are opposite. An upper press roller is arranged between the two eccentric sleeves on the upper portion in a clamped manner, and the two ends of the upper press roller are connected with the two eccentric sleeves on the upperportion through bearings. A lower press roller is arranged between the two eccentric sleeves on the lower portion in a clamped manner, and the two ends of the lower press roller are connected with the two eccentric sleeves on the lower portion through bearings. By means of the distance-adjustable synchronous roller, the distance between the upper press roller and the lower press roller can be increased or decreased, and the lower press roller synchronously and reversely rotate by the same angle while the upper press roller is adjusted.

Description

technical field [0001] The invention relates to the field of pressure rollers, in particular to a pair of synchronous rollers with adjustable spacing. Background technique [0002] Pressure rollers are often used in daily life. The counter roller is a kind of pressure roller, and the counter roller has a higher rolling effect on the material. It is common that one active pressure roller and another driven pressure roller squeeze each other. But in life, sometimes three-dimensional embossing is required, such as setting a punch on the upper pressing roller and a die on the lower pressing roller. Since the speeds of the upper pressing roller and the lower pressing roller are not equal, the material will be pulled and torn, often The molding quality is very poor and does not meet the requirements. At this time, it is necessary to use a synchronous pair of rollers with the same angular velocity between the upper pressing roller and the lower pressing roller. Synchronous counte...

AI Technical Summary

Problems solved by technology

Synchronous counter-rollers in the prior art often have separate motors for the upper and lower press rollers. Even if the same speed is set, due to the design error of the motors, absolute synchronization cannot be achieved, and a small misalignment will cause the material rollers to pressure failure

In addition, in the prior art, the process of adjusting the distance between the rollers is cumbersome, the adjustment is not accurate, and it is difficult to fix after adjustment
